8. In terms of the incidence and classification of diabetes, maternity nurses should know that: a. Type 1 diabetes is most common. b. Type 2 diabetes often goes undiagnosed. c. Gestational diabetes mellitus (GDM) means that the woman will be receiving insulin treatment until 6 weeks after birth. d. Type 1 diabetes may become type 2 during pregnancy.

### ANS: B Type 2 diabetes often goes undiagnosed because hyperglycemia develops gradually and often is not severe.

## Step1: Understanding the types of diabetes### There are three main types of diabetes: Type 1, Type 2, and Gestational Diabetes Mellitus (GDM). Type 1 diabetes is often diagnosed in childhood and is characterized by the body's inability to produce insulin. Type 2 diabetes, often diagnosed in adulthood, is characterized by the body's inability to use insulin properly. GDM is a condition that occurs during pregnancy, characterized by high blood sugar levels that are not due to gestational diabetes.## Step2: Analyzing the options### Option A suggests that Type 1 diabetes is the most common, which is incorrect as Type 2 diabetes is the most common. Option C suggests that a woman with GDM will be receiving insulin treatment until 6 weeks after birth, which is not necessarily true as insulin may or may not be needed. Option D suggests that Type 1 diabetes may become Type 2 during pregnancy, which is not accurate as people do not go back and forth between types 1 and 2 diabetes.## Step3: Identifying the correct answer### Option B suggests that Type 2 diabetes often goes undiagnosed because hyperglycemia develops gradually and often is not severe. This is the correct answer as it aligns with the known characteristics of Type 2 diabetes.
